#7 Goldust
Earlier this year, it had been rumoured that Goldust had requested his release from WWE and would be heading to AEW to work alongside his brother, Cody, but reports were scarce.
While it was all very hush-hush, Goldust has since confirmed that he has left WWE, and will be competing at AEW's landmark premiere event Double or Nothing in a match against real-life brother Cody.
Goldust's wrestling career spans 30 years, a lot of which has been spent in WWE - but Rhodes also spent time in WCW and TNA. In WWE, though, the 49-year-old is a three-time Intercontinental Champion and nine-time Tag Team Champion, with three Tag Team title reigns, too, but knee injuries blighted the last year of his WWE career.
Goldust sent out an emotional statement confirming that he had requested, and been granted, his release - and hinted that he may retire after his Double or Nothing match, or at least work limited dates, having recently embarked on an acting career.
#6 & #5 - The Revival
Having been one of the top teams in NXT, having won the Tag Team Championships twice, The Revival were a team who jumped onto the main roster with a heap of high expectation.
Until recently, Dash Wilder and Scott Dawson had found that form hard to replicate but, since asking for their release while still in their ring gear after a match, and with AEW teasing the signing of the pair, their career has seen its own revival in WWE, where they recently held the WWE RAW Tag Team Championships, only dropping them at WrestleMania to Zack Ryder and Curt Hawkins.
Top guys out? Not yet, at least.
